BGP analytics

Hi; I'm searching for people who are doing analysis of BGP data on production networks. I'm particularly interested in graphing growth of particular AS_PATH regular expressions. I realize I could scrape this data using expect or similar, but I'm looking more for solutions already operating using zebra, bgpd.pl, or similar toolsets. An added bonus would be the ability to throw this kind of data into an SQL database. I know about CAIDA and routeviews; i'm more interested in this within my own network. Please reply off-list -- i'll post a summary. Thanks, Tim
